Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a low-voltage incoming line cabinet with an external wiring structure. Background Art

[0002] The incoming line cabinet is a switch cabinet that introduces power from the outside. It can introduce 10kV power from the power supply network and send the power to the 10kV bus through the switch cabinet. The incoming line cabinet can distribute the power and also has multiple protection functions for the power incoming end. The incoming line cabinet is equipped with electrical components such as vacuum circuit breakers, disconnectors, three sets of three-coil current transformers, lightning arresters, live indicators, voltage transformers, and wires. When in use, the incoming line cabinet needs to be connected to the external wiring to energize the incoming line cabinet.

[0003] After searching, the Chinese patent with the announcement number CN210273097U discloses a low-voltage incoming line cabinet with an external wiring pipe, including an incoming line cabinet body, a plurality of incoming line holes on the side end surface of the incoming line cabinet body, an incoming line seal provided at the opening of the incoming line hole, the incoming line seal including a hanging plate and a sealing plate, a hanging groove provided in the hanging plate, an incoming line pipe hung in the hanging groove, a hanging edge provided at the top of the incoming line pipe, and an end sleeve sleeved at the pipe opening at the bottom of the incoming line pipe. The low-voltage incoming line cabinet with an external wiring pipe, by providing an incoming line seal and hanging the incoming line pipe to the incoming line seal, allows cables from the outside to be connected to the inside of the incoming line cabinet body through the incoming line pipe, without the need for additional connection ports, and by sleeved at the pipe opening at the bottom end of the incoming line pipe, the cable surface is prevented from being worn due to constant friction with the pipe opening of the incoming line pipe, which may easily cause leakage.

[0004] This patent can only protect cables from wear and tear, but cannot arrange and fix multiple cables of different diameters entering the incoming cabinet. This can easily lead to problems such as messy cables that are inconvenient to find, and cables that easily shake and fall off accidentally. At the same time, it cannot accelerate ventilation and heat dissipation for the incoming cabinet connected to multiple cables, which is not conducive to improving the service life of the equipment inside the incoming cabinet.

The wire entry tube 301 can facilitate the installation of cables, the card plate 302 can fix the soft silicone 303, and the soft silicone 303 can fix the cables and The card plate 302 is directly sealed, the card plate 302 is inserted into the inlet pipe 301 and is fixedly connected to the soft silicone 303, the side wall of the card plate 302 is fixedly equipped with a connecting rod 304, the connecting rod 304 can connect the ring 306 and the card plate 302, the inlet pipe 301 is fixedly equipped with a limiting ring 305 and the side wall is provided with a ring 306 fixedly connected to the connecting rod 304, the limiting ring 305 can limit the ring 306, and the ring 306 can fix the card plate 302 through the connecting rod 304.

[0030] By pulling the card plate 302 to move the soft silicone 303, the card plate 302 and the soft silicone 303 can be pulled out of the wire inlet pipe 301. The two card plates 302 are opened, and the two soft silicone 303 are opened as well. The cable is passed into the wire inlet pipe 301, and then the cable outside the wire inlet pipe 301 is passed between the two soft silicone 303. By closing the two card plates 302, the two soft silicone 303 are closed. The two soft silicone 303 squeeze the cable, and the card plate 302 squeezes the soft silicone 303. The soft silicone 303 deforms and fills the cable and the card plate 302. The soft silicone 303 can seal the space between the cable and the card plate 302, and then the card plate 302 is inserted into the wire inlet pipe 301, and the card plate 302 drives the ring 306 to move through the connecting rod 304, and the ring 306 can drive the card plate 302 to be fixed through the connecting rod 304, and can fix the card plate 302 in the wire inlet pipe 301, and the card plate 302 can fix the cable in the wire inlet pipe 301 through the soft silicone 303. Each cable is fixed in each wire inlet pipe 301, and the cables can be arranged.

[0031] like Figure 1-2As shown, a heat dissipation component 4 is installed below the top plate 1, and the heat dissipation component 4 is used for heat dissipation inside the incoming line cabinet. The heat dissipation component 4 includes a fixed box 401 fixedly mounted on the bottom surface of the top plate 1 and a symmetrically installed heat dissipation fan 402. The fixed box 401 can fix the heat dissipation fan 402, and the heat dissipation fan 402 can dissipate heat inside the box 5. The heat dissipation fan 402 is symmetrically mounted on the side wall of the fixed box 401, and the side wall and bottom surface of the fixed box 401 are respectively fixedly mounted with a through plate 403 and a filter plate 404, and the through plate 403 can connect the air inlet pipe 6 and the fixed box 401, and the filter plate 404 can filter the air entering the inside of the box 5.

[0032] By starting the cooling fan 402, the air flow inside the fixed box 401 is driven. The air flow inside the fixed box 401 drives the air flow inside the air inlet pipe 6 through the through plate 403. The air flow inside the air inlet pipe 6 drives the air outside the air inlet pipe 6 to enter the through plate 403. The external air enters the fixed box 401 through the through plate 403. The external air inside the fixed box 401 is filtered through the filter plate 404 and then enters the interior of the box 5, which can dissipate heat for the air inside the box 5.

The slide rail 701 can limit the push rod 702 and the spring 703, and the push rod 702 can be connected to the snap ring 8. The push rod 702 is passed through the slide rail 701, and a spring 703 located between the two push rods 702 is fixedly installed in the center of the slide rail 701. The spring 703 can give thrust to the push rod 702.

[0034] By pulling the two push rods 702 in opposite directions, the two push rods 702 are brought closer to each other, the push rods 702 squeeze the spring 703, and the push rod 702 is pulled out of the snap ring 8. The push rod 702 loses the fixation of the snap ring 8 and drives the slide rail 701 to lose its fixation. After the slide rail 701 loses its fixation, it drives the top plate 1 to lose its fixation, which can facilitate the disassembly of the top plate 1. By pulling the two push rods 702 in opposite directions, the two push rods 702 are brought closer to each other, the push rod 702 squeezes the spring 703, and the spring 703 gives the push rod 702 a thrust, clamping the top plate 1 on the top of the box body 5, so that the push rod 702 is aligned with the snap ring 8, and the push rod 702 is loosened. The push rod 702 is inserted into the snap ring 8 and fixed. The snap ring 8 is fixed by the box body 5. The push rod 702 is fixed to the top plate 1 through the slide rail 701, and the top plate 1 can be fixed on the box body 5.
